SPECIFICATION forming part of Letters Patent No. 764,585, dated July 12,1904.

Application filed May 14, 1903. Serial No. 157,082. (No model.)

To all Lu/tom. it may concern.-

Be it known that I, HARRY F. HEALEY, a citizen of the United States, anda resident of Chelsea, in the county of Suffolk and State ofMassachusetts, have invented a new and useful Improvement in Means forCutting Flat Sheets of Cardboard, Paper, or other Material into CardsHaving Beveled Edges, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature.

The invention relates to a method of and means for cutting flat sheetsof cardboard, paper, or other material into cards having a beveled edge.

Heretofore to form from flat sheets individual cards which shall have abeveled edge it has been customary to first cut from the fiat sheetscards having straight edges and subsequently by a separate manipulationto change the straight edge of the cards to a beveled or inclined one.My invention accomplishes both the cutting of the card from the sheetand the beveling of its edge as one operation.

In practicing my invention I employa cutting mechanism which is adaptedto receive and hold any desired number of sheets of cardboard, paper, orother material, preferably in a somewhat staggered relation to eachother or so that the side of the stack of sheets presented to the cuttershall be inclined, and acutting blade which has an inclined shearingmovement with respect to such stack and whereby there is formed aninclined or beveled edge to each sheet of the stack. Usually sheets ofcardboard or other material of a size to form a number of cards areused, and in order to provide each edge of each card with an inclined orbeveled finish it is necessary to turn the stack of sheets and tosubdivide them according to the size of the cards which it is desired toobtain. Of course for the formation of cards having each edge beveled itwill be necessary that the stack from which said cards are producedshall be presented I four times to the cutting-knife, once for eachface, and it will also be necessary to arrange the cards of such stackin the inclined or staggered relation to which I have above referred.

While I have referred to the making of cards having beveled edges, Iwould not, of course, be understood as limiting the invention to themanufacture of cards only, but may employ it in producing such edges oncardboard, paper, or any material that may be cut by the knife and forany purpose or use desired.

I will now describe the invention in detail in conjunction with thedrawings, wherein" Figure 1 is a view in end elevation of my improvedcutting-machine. Fig. 2 is a view in vertical section thereof upon thedotted line 2 2 of Fig. 4. Fig. 3 is a detail view enlarged toillustrate the operation of the machine. Fig. 4: is a view in frontelevation of the complete machine.

In the drawings, A represents the bed of the machine, upon which thesheets are held while their edges are being cut to a beveled form. Thebed is of any desired extent, is flat, has the cross-recess a forholding the cutting-stick a, an inclined gage (0 against which the backedges of the stack of sheets is caused to bear and by which theinclination of the front edge of the stack is determined. This gage isadjustable upon the bed with respect to the cutting-stick in order thatit may be set to the width or length which it is desired that thefinished cards shall have. It is in the form of a metal plate having asmooth front surface and is mounted upon the carriage a, to which it issecured by screws or in any other desired way. The carriage is arrangedto slide in the guideway a in the bed, having a tongue a to enter theguideway. The carriage is held in the guideway by a plate a, whichslides upon the under surface thereof and which is fastened to thecarriage by screws or bolts (/7. This plate bears a nut a", with whichthe worm a ofthe worm-shaft a engages. This wormshaft is supported by ahanger a and by the frame of the machine, and it is turned by the handlea at the front of the machine. The turning of the shaft causes the guideto be moved back or forth on the table, according as may be desired.Upon each side of the bed, extending upward and backward from the sidesof the frame, are the frame extensions B B. In each of them is theguideway 7), which is inclined to the bed, and these guideways serve toguide the movement of the head C, which has attached to it near itslower edge the knife-bar C. This head extends through the guideways, isconsiderably longer than the distance between the two guideways, and hasat each end a trunnion c in the shape of a sphere, which is held in acup or socket bearing 0' at the upper end of the connecting-rods c 0,respectively. These connecting-rods are by similar sockets attached attheir lower ends to the balls or spheres 0 on the ends of crankpins 0 onthe crankshaft 0. The balls upon. the head and upon the crank-shaft areso located as to permit universal movements of the connecting-rods. Thecrank-shaft is turned by means of the gear 0 on the crank-shaft and thepinion c on the pulley-shaft 0, which meshes with the gear 0 The head 0is attached to the stationary cross-bar 0 of the frame by a link 0,which is pivoted to the cross-bar and to the head and which causes thehead to be moved laterally as it is being moved downwardly and so as togive it a drawing cut. It will be seen that because of the inclinationof the guides and because of the link the head, and consequently theknife, is given an inclined forward movement toward the cutting-stickand also a lateral movement at the same time, and that theconnecting-rods and. their operating devices are arranged to operate inan inclined direction corresponding with the inclination of the head andguides, and that the connecting-rods are also attached to the head to beswung laterally with it while they are moving in their inclined paths.

I prefer that the crank-pins be so set that one shall be slightly inadvance of the other and so that the head and the knife-bar shall varyas to their inclination from end to end, thereby causing the cuttingedge of the knife to have an additional shearing action to that causedby its lateral movement and due to the fact that the cutting edge of theknife is not quite parallel with the surface of the cards or work, andso that the stress or force of the plate is not taken entirely by onecard, but is distributed over two or more. While this is not anessential element of the invention, it is of advantage in lightening thework upon the knife and in getting a somewhat cleaner cut and also inreducing any liability of forcing or pressing down a portion of thecards immediately adjacent to the inner surface of the knife.

To hold the assembled cards upon the bed in their gaged position, Iemploy a presserbar D, having the flat pressing-surface (Z and theinclined surface d. This bar has ends which are mounted in the verticalguideways (Z in the frame extensions B, and it is moved vertically insaid guideways toward and from the bed by means of the screws (Z one ateach end, which screw into a threaded. hole therein and which screws areturned by the handwheel d, shaft d, and shaft (1 the shaft d beingconnected with the shaft d by bevelgearing and the shaft with the screws62 by bevel-gearing. (See Figs. 2 and 4.)

The knife-plate is attached to its head to be removable in any desiredway.

In operation the gage a is adjusted upon the bed to any desiredposition. The cards or sheets are arranged upon the bed with their backedges against the gage and their front edges occupying an inclinedrelation to each other and extending backward and upward from thecutting-stick and beneath the cutting edge of the knife. The presser-baris then moved downward upon them to' clamp them to the bed with anydesired pressure and the knife-block and knife caused to make a fullreciprocation, which causes the knife to be moved with a shearing outupon an inclined plane substantially parallel with the front edge of thecards and severing from the cards pieces which are practicallytriangular in shape and which leaves each card of the stack with acontinuous inclined or beveled edge upon one of its sides. The knifewhen used in cutting the larger sheets into smaller cards workssubstantially in the same way, with this exception, that when it iscutting a stack of cards in two it provides beveled or inclined edges atthe same time for both divisions of the stack-those that are inside theknife and held'by the presser-bar and those which are upon the bed uponthe front side of the knife. It will be understood that for beveling allthe edges of the cards the stack of cards is rearranged against the gagefor each successive cut.

While I have described my machine as having a horizontal table andguideways at an angle thereto, I wish it understood that I consider thatmy invention would be embodied in a machine in which the guideways forthe knife were vertical and the table was at an angle thereto.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States 1. The means for providingbeveled edges to cards or other articles comprising a bed for thesupport of the cards, an inclined gage on the bed against which the backedge of the cards bears, a presser adapted to be moved upon the cards toclamp them to the bed and with portions of the cards in front of 'thepresser but below a cutting-knife, a cuttingknife and means forreciprocating it upon an inclined path toward and from the bed.
